3 Claims. (of. 134-93) My invention relates to a new and improved device for washing bottles, more particularly infants nursing bottles.

The principal object thereof is to provide a new and improved device for thoroughly cleansing and washing infants nursing bottles, which device can be used simply by connecting the same to any water faucet or outlet.

Another object of my invention is to provide a bottle washer in which as many as seven nursing bottles may be properly cleansed and washed at the same time, provision being made for such a number because that constitutes the normal one day feeding complement for the average infant. 7

Another object of my "invention is to provide 'a bottle washing device which will supply several streams of cleansing liquid to each bottle when connected to a water faucet, the device having means for thoroughly mixing a, cleansing material with the water as the water passes therethrough.

Still another object of my invention is to provide a bottle washer which will thoroughly and effectively cleanse the interior surfaces of each bottle as well as the exterior surfaces thereof including the external neck and shoulder portions of the same, in a single washing operation. Still another object of my invention is to provide an infants bottle washing appliance which is compact, comparatively light in weight, and extremely easy and simple to handle and operate.

Still another object of my invention is to provide abottle washing device which can be wholly placed within a sterilizer and 1 employed to sterilize the previously washed and rinsed bottles, without the necessity of removing any of the washed bottles from the device. l

Still another object of my invention is to provide a device which can be used for two purposes, namely, as a bottle washer and also as an accessory device for a sterilizer.

Other objects of the invention will be stated in the annexed description and drawings which illustrate preferred. embodiments thereof.

Fig. 6 is a sectional view, partially in elevation, 01 a modified form of the device, showing in ."detail the construction of the modified bottom rp'ortion of the device, the remainder of the de- 'vice being shown broken away for the conven- -ience of illustration. j; 1 Fig. 7 is a view siinilar to Fig. 6 showing one I ,of the bottles in position to be washed and also showing a cap covering and closing one of the nozzle members.

-.,Fig. 8 is a. sectional viewon the line 8--8 of -Fig. '7, with the mixing compartment and the ottles removed from the device, showing one of he cap members and part of the device broken away.

" 'Fig. 9 is a sectional view of a modified form Referring to the first embodiment (Figs. 1 to v 5), particularly to Fig. 1 thereof, the device ineludes a frame consisting of two pairs of upright supports I, each of said pairs of supports being of different length, the longer pair terminating at their upper ends in hooked portions 2 which serve as handles by which the device may be lifted, handled or carried. The said four sup- Fig. 1A is a'detail view of one of the removable closure members which is provided with the upwardly directed nozzles.

' Fig. 21s a sectional view on the line 2-2 of bottles beingiremoved from the device.

ports are secured at their respective lower ends "to'the base portion 3 of the device by means of screws or rivets 4. 1 A circular bottle rack 5 having the peripheral depending annular flange 6 is secured to all four supports I by means of the screws or rivets l which pass through said supports and said depending flange. It will be noted that said rack 5 is spaced from and is located above base portion 3 and that said flange 6 is secured to the pair of shorter supports i, adjacent the upper ends of said supports.

Rack 5 is provided with a plurality of spaced openings 8 adjacent the perimeter thereof, all 'of the said openings being of the same size and shape and all having the depending annular flange ll. Said openings 8 receive the bottles B which are held in an inverted position by means of rack 5.

As shown in Fig. 1, the base portion 3 of the device is hollow, thus forming a distributing chamber or compartment I0. Said chamber I0 is of chamber l0. It is to be understood that my. invention is not to be limited or restricted to any particular number of such openings; The reasonfor the selection and provision of seven will hereinafter be explained.

Each of openings l2 in cover H are surrounded by an internally threaded upstandingwall or shoulder [3 which i adapted to receive the (ex-'- ternally threaded removable closure member I4. EachLof'said-members. l4=is provided. with an upwardly' directedandscentrally located nozzle l5 and apluraiity'eofobliquely disposed jet openings I6; fcnrxinnumber'... The top-face of each of said members l4 tapers downwardly from the peripheraliedge thereoftowardsthe base of nozzle 1 5.

The function of said 'nozzle l5 and openings willihereinafterzbe described. When screwed into -position,:-each closure member [4 will close :each opening 12in: cover of rchamber ill, the only means of communication thenbeing-thenozzles 15 iandcopenin'gslfi. Imthe closed position shown ini-Fighl, the ibottomifacepof member 14 is flush with the bottomrface of cover' I l.

As shown in Fig. 3, four spaced radial supporting pins :11 project:* laterally from the upstanding sidewall .of 1891011 :nozzle l5; each .oppoe sitely: disposed pair :of pins being in; alignment. .Thez'saidz pins 5.! I .mayi'be formed integrally with nozzle Hi, the said pins serving as supports aupon whichithe inverted bottles 33 are positioned for washing. It will be notedthatpins H are spaced from the top face of closure member 14.

As shown in Fig. 1, cover ll of chamber lll'is provided .with the centrally located and upwardly projecting inlet-l8. Removably mounted upon said inlet is the cylindrical and downwardly tapering-mixing chamber 19 having an outlet pipe 20 which-communicates and is aligned with inlet pipe l8 of chamber l0. Mixing chamber [9 is providedwith the removable cover 2 I: having the inlet .22 integral therewith. I have designated said-chamber "l9 as a mixingchamber for the reason that'the cleansing or soapy material is placed within-said chamber to be intimately intermixed withthe water passing therethrough. It will-be noted that aportion of outlet piPeZEl is curved-at 23 so that said pipe is not in alignment with inlet pipe-22. Oneadvantage of this construction is that the water entering chamber [9 through the inlet pipe 22 will strike and impinge against said curvedsurface 23"of outlet pipe 20 thus "swirling:andtagitating the water and the cleansing. material so :that a proper intermixing and dispersion isprocured. A screen 24 is'secllred to the upper open-.endof outlet pipe 20 to prevent the-passage oregress of any impurities in the water or any-undissolvedlarge particles ofthe cleansing material, M 1

' As shown in Figs. 1 and ig-an extensible rubber or flexible hoseor tubing 25 is secured to inlet pipe 22, the opposite end of said hose or tubing being connected .to a water. faucet F or an outlet of any water supply by means of the coupling element '25 and a clampband 21. .In thi manner, the device is supplied with the water necessary to wash and rinse the bottles. washingdeyice. is .used and operatedinthe 0 owingmann'er: J f 'Thejbottles Bare inverted and placed in a open;

-- mixing chamber.

ings 8 of rack 5, the neck of each bottle resting upon the supporting pins I! as shown in Fig, 1. In this position, each nozzle I5 extends into the neck portion of each bottle. Cover 21 f mixing "chamber l9 isthen unscrewed and the required or predetermined amount of soap powder or powdered cleansing material is placed within said Cover 2| is then replaced and the-entire'device is set in a sink or wash basin.

Inlet 22 of mixing chamber I9 is then connected to faucet F by means of the rubber hose 25. The

- faucet is thenopened, the course of the water indicated bythe'arrows shown in Fig. 1 being as follows":

From tubing 25, the water passes through the inlet pipe 22 into the mixingrchamber l9; striking against'curved portion 23 of outlet pipe 20. The cleansing material within mixing -chamber l 9 agitated by the entering =water. is: intermixed therewith and the resulting cleansing liquid leaves chamber! through outlet pipe 20 and" thence passes into compartment-l0 in base portion 3 via inlet l8. From: compartment l0, the-c1eansing liquid is jetted intotheinterior of each bottle through nozzles l5 and against the'exterior surfaces thereof including the external. neck:- and shoulder portions of each .bottl through jet openings l6. In this manner; five streams of cleansing liquid are directed under'pressure't-o each bottle, one large stream to the interior; of the. bottle and four smaller .angularly directed streams to the exterior surfaces thereofincluding the external neck and shoulder. portions thelat ter being the area of-the bottle :which ultimately receives. the :feedingnipple; The washing operation is continueduntilall the. powdered cleansing material in mixing chamber I9 is consumed'and then clear water is permitted topass through so that the. bottles can be properly rinsed to remove any trace of cleansing materialthat-may-have adhered to any of the bottles.

By reason of the fact that the supportingzpins H are spaced from each other,and spacedir'om the base of nozzle-l5 so that the bottle .willinot rest upon the nozzle, the sprayed-water oricleansin-g liquid can leave the interior of each bottle 13 by passing through the spaces between saidsupporting pins and thence overflowing -over upstanding wall 13 and'into the .sink oribasin;v

The pressure of. the..waterv that flows iromithe ordinary faucet or water outlettogether with the increase of said pressure by the arrangement-and construction of the various parts of the device through which the water passes is sufilcient" to project the cleansing liquid or-water with suflbcient force into-the bottles tobe washed as :well as against the exterior surfaces thBZCOfr As-many as-seven bottles can be cleansed, washedciand rinsed in one washing operation .of only 'IBI'IfGW minutes duration. Provision "is made fort'tthe washing of seven bottles forzthe reason that the normal daily feeding complement of the average infant is siX bottles of milk and xonexbottlepf water. In this manner; a 'full ":days :supply of bottles may be "prepared in a single washingfoperat-ion. Of' course; less. than seven: bottles. may bewashed with any devicepifndesired. Ifgfor example, it is desired to.:wash only.iive bottles,

then. two of the closure .membersl l are-:covered integral with ;.the cover 31 of chamber 32 in- ;stead of b eingjremovable as'inthe "case ofrthe first'described'embodiment -(Figs;..1 to 51v Other.-

wise, the two embodiments are identical in structure and configuration in all other respects. The second embodiment is used and Operates in the same manner as the device of the first embodiment.

Provision is made in the second embodiment for the washing of seven bottles in a single washing operation. If it is desired to wash a lesser number, then the nozzle members which are not used are each covered by a threaded cap 33 which is received by the upstanding internally threaded wall 34 which encircles each nozzle member 30. This is clearly illustrated in Figs. 7 and 8.

It will be noted that wall 34 is integral with nozzle members 30 and the cover 3| of chamber 32.

Referring to Figs. 9 and 10, this illustrates a modified form of cylindrical mixing chamber 40 particularly suitable for the use of cleansing or detergent tablets. The mixing chamber 40 is provided with a cover 4i having the integral frustoconical or tapered inlet nozzle 42 depending therefrom.

Mixing chamber 40 is also provided with the annular recess 43 and four individual countersunk tablet receiving recesses 44 communicating therewith. A longitudinal outlet pipe 45 is located below inlet nozzle 42, said outlet pipe extending above annular recess 43 and communicating with the four tablet receiving recesses 44 by means of a plurality of orifices 46.

It will be noted that the base of inlet nozzle 42 extends above and beyond annular recess 43 and tablet receiving recesses 44 so that when water passes through said inlet nozzle it will be directed as shown by the arrows in Fig. 9 into said annular recess and into the tablet receiving recesses, after which it rises above said annular recess and leaves the mixing chamber 40 via the outlet pipe 45.

The four individual recesses 44 may be in the form of a single-continuous recess 44A as shown in Fig. 11. In this case, an annular pre-shaped ring of soap 443 (as shown in Fig. 12) can be placed within said continuous recess 44A.

After the nursing bottles have been cleaned, washed and rinsed, the device is placed within a sterilizer for sterilization of the bottles. It is not necessary to remove any of the bottles from the device when placing the same in the sterilizer. If desired, the mixing chamber may be removed preparatory to sterilization. In any event, sufiicient water should be left in the chamber in the base of the device so that sufiicient steam will be produced for effective sterilization.

With the use of my new and improved device, the bottles may be first washed with hot water, then a mixture of hot and cold water, and finally rinsed with cold water simply by connecting the device to any water faucet or outlet.

There has been illustrated and described 9 preferred embodiments of my invention but it is obvious that numerous changes and omissions may be made without departing from its spirit. For example, my device can be of any desired shape although it has been illustrated as being circular. Likewise, although my device has been constructed to permit the cleansing and washing of seven bottles, its construction can readily be modified to accommodate a smaller or larger number of bottles than seven.

My device can be made of any suitable metal, plastic, ceramic, or any other suitable material.

I claim:

1. A bottle washing device comprising means to support a bottle in an inverted position, a water nozzle extending vertically into the mouth of the bottle, a chamber extending to a level considerably higher than said nozzle, an outlet pipe having an inlet in said chamber, having a curved portion positioned in said chamber and having an outlet connected to said nozzle, and an inlet pipe connected to a Water supply and having an outlet in said chamber above said curved portion of said outlet pipe.

2.
